mine extension drill rod. The introduction of tapered threads reduced stress concentrations at thread connections, minimizing the risk of fractures. Additionally, the implementation of advanced coatings such as titanium carbonitride (TiCN) provided an extra layer of protection against abrasion and wear, extending the service life of the rods significantly.
thread drill bit. Too much pressure can cause the bit to break or the thread to be cut improperly, while too little may result in an incomplete thread or a loss of precision. Therefore, operators must be well-versed in the specific properties of the materials they are working with, as well as the capabilities and limitations of their tools.
fiberglass pipes and fittings for ship building. Unlike steel and aluminum, fiberglass does not rust or corrode when exposed to water or other harsh environments. This means that fiberglass pipes and fittings can withstand the rigors of sea water and other harsh conditions without requiring frequent maintenance or replacement.
